SLATE=SEPARATOR FOR COAL-CHUTES.

SPECIFICATION formingpart of Letters Patent No. 266,448, dated October 24, 1882,

Application filed June 27. 1882.

To all whom it may concern:

Be it known that we, JEREMIAH S. FAHRIN- GER and MARTIN URIPPEN, of Dickson Borough, in the county ofLackawana and State of Pennsylvania, have invented a new and Improved Slate- Separator for Goal-Chutes, of which the following is a full, clear, and exact description.

The object of our invention is to facilitate 1:: the removing of pieces of slate from coal.

Reference is to he had to the accompanying; drawings, forming partof this specification, in which similar letters of reference indicate corresponding parts in both the figures.

, Figure lis a perspective view of a coalchute provided with our improved slate-separators. Fig. 2 is a plan view of the same.

On the upper side of the bottom of a coalchute, A, a series of plates or aprons or sepa- 2o raters, B, rest, which plates or separators are secured to the sides 0 of the chute and are inclined toward the lower end and the longitudinal middle line of the chute. The plates or separators B are alternately attached to opposite sides of the chute, and they alternately project in opposite directions, as is shown in. Fig. 2. Each plate or separator has its bottom edge cutout in such a manner that a longitudinal slot, 1), will be formed at the bottom 33 of each plate or separator, which slots gradually increase in width from the upper toward the lower ends. Between each plate or separator B and the sides of the chute an aperture, E, is made in the cleats, and from these aper- 5 tures chutes lead to the slate-receiving cars.

The lower or outer ends of the plates or separators are preferably braced by bending the plate of which the separator is made so as to form a triangular pocket when attached to the side of the chute, or the free ends of the separators can be bracediu any other suitable manner.

As is well known,the pieces of slate that appear in coals are all flat. As the coal runs 5 down the chute thelumps of coal will strike one plate or separator, will be deflected in its course and thrown against the next lower plate or separator, and, so on. In this manner the coals will pass through the chute in a zigzag line, striking each separator or plate B. Every (No model.)

time the coals strike a separator the coals only will be deflected, as they cannot pass through the slots D, but the fiat pieces of slate pass through the slots D and through the apertures E into the slate-chutes, and thus a part of the slate will be removed each time the coals strike against a plate or separator. If a piece of slate catches and isjammedin the slot D, the following pieces of coal \villdrive it downward into the wider part of the slot, through which it can drop.

Having thus fully described our invention, we claim asnew and desire to secure by Letters Patent v 1. In aslate-separator, the combination, with a chute, of a series of plates projecting downwardly and inwardly from the sides of the said chutes, and each having a tapering opening between its lower edge and the bottom of the chute forthepassage of the slate, substantially 77 as herein shown and described.

2. In aslate-separator, the combination, with the chute A, provided with apertures E, of a series of plates, B, projecting inwardly and downwardly from opposite sides of the chute, 7 which plates have slots D formed in the lower edges, substantially as herein shown and described, and for the purpose set forth.

3. In a slate-separator, the combination, with the chute A, provided with apertures E, of a series of plates, 13, projecting inwardly and downwardly from the sides of thechute, which plates 13 have slots D increasingin width from the upper toward the lower ends formed in the lower edges, substantially as herein shown and described, and for the purpose set forth.

4.. The combination, with the chute A, of the plates or separators B, projecting inwardly and downwardly and alternately from opposite sides, the slots D in the lower edges of the 0 plates, and the apertures E, formed in the chute A, between these plates and the sides of the chute, substantially as herein shown and described, and for the purpose set forth.
